The Orbitz Insider Index has good news for travelers still searching for flights to or from airports that have a less frenetic pace than their larger counterparts. For the second straight year, Orbitz is revealing its top 10 list of the least busy Thanksgiving airport alternatives.

While these airports aren't necessarily the least busy in the top 100 list, they are the least busy alternatives relative to other major airports serving destinations in the area, and should prove easier to navigate over Thanksgiving.

This year, the Insider Index looked at the top 100 U.S. airports based on arriving, departing and connecting flights to determine the most and least busy for Thanksgiving travel between occurring between 11/23/10 and 11/29/10.

Chicago O'Hare International once again outpaced all other domestic airports over the Thanksgiving holiday, with 20 percent more flight activity than second place Los Angeles International. Boston Logan International ranks third on our list of busiest airports, with the three New York tri-state airports capturing the fourth (La Guardia), seventh (John F. Kennedy) and eighth spots (Newark)
